By encouraging food tracking, calorie counting, and the consumption of mostly fruits, veggies, and lean protein (sugar and unhealthy fats are discouraged), you can theoretically lose as many pounds as you want with WW, as long as you do not deviate from your established plan. And, because WW does not prohibit any foods, it is one of the most sustainable diet plans out there. Once you get the hang of the points system, you can even do it by yourself for the rest of your life. 
"Your body begins to work differently. This study proves that small amounts of nourishment throughout the day are better than the same amount of food concentrated in three big sittings. If we feed the body at regular intervals we send a signal to the body that it doesn't have to store calories. Conversely, when we skip meals we send just the opposite signal for the body to store calories, creating a negative effect on the metabolism." — Dr. Wayne Scott Andersen, co-founder and Medical Director at Take Shape For Life
"Use a VersaClimber or take a VersaClimber class. These machines are still not that common, but in my opinion they are far more effective for weight loss than other forms of cardio. They require you to use a large portion of your muscles and it's functionally better for you than other forms of cardio like spinning. Everyone is talking about Rise Nation in LA at the moment as they are the first dedicated VersaClimbing studio. There's no harder cardio workout I have tried. To lose fat you have to put in the work. — Dan Roberts, celebrity trainer and creator of Methodology X
Even if you do meet your goal, it's nearly impossible to keep off the weight over the long term: "The amount of restriction required [to maintain that number] will make you so hungry that you’ll eat everything in sight—it’s survival instinct," Dr. Seltzer says. And since calorie restriction gradually slows your metabolism, your body will be less prepared to burn the foods you binge on, he adds. That could mean gaining more pounds than you lost in the first place.
To help you on your way, the WW app allows you to track your food, weight, and activity, look up the Smart Points value of each food, chat live with experts, get over 4,000 recipes, sync your fitness device, scan foods, and find daily inspiration on Connect, a members-only digital community. The app won the 2019 People’s Voice Award Webby for Best Practices thanks to its “advanced practices in app and mobile site development.”
Incorporate a 12-hour fast. Don't panic — most of this fast occurs while you sleep. Restricting your eating to 12 hours a day may help you lose weight, according to one study.[14] You should still eat your recommended daily calories, but limit yourself to only eating during a 12 hour period. So you might eat breakfast at 7am and cut yourself off from eating after 7pm. Though it is not fully understood, this 12-hour fasting period may cause your body to switch from burning food to burning fat.
"Research continues to support the role of a high-protein diet and weight loss, however, we don't want to reach those protein needs exclusively with animal proteins. Plant proteins found in beans not only help us feel full and stabilize blood sugar but beans are associated with longevity. Who cares about being skinny if you die young?" —Jennifer McDaniel, MS, RDN, CSSD, LD, food and nutrition expert
Phase 1: This is the “metabolism reboot” phase, and the most restrictive part of the plan (but it only lasts two weeks, so that’s good news). You’ll basically cut all carbs from your diet, as this phase allows for no more than 40 grams of net carbs per day. The purpose of this first phase is to reset your metabolism and help your body burn fat instead of carbs. Carb lovers beware! You will not be able to eat bread, pasta, rice, and some fruit, which might be too restrictive for some. Because of this strict approach, you’ll most definitely see weight loss results at the end of the plan’s first seven days.
The fad military diet consists of low-calorie, odd food pairings such as bun-less hot dogs with banana, carrots, and broccoli. “Any diet like the military diet that severely limits the amount of calories you consume or eliminates one or more entire food groups puts any individual at risk for nutrient deficiencies,” says Kyle. “This can be more harmful than holding onto those 10 extra lb you’re trying to lose.” (32)
The Dietary Approach to Stop Hypertension, like the TLC described earlier, is endorsed by the National Heart, Lung, and Blood Association, the American Heart Association, and the 2015 Dietary Guide for Americans. It was developed with the purpose of helping people reduce blood pressure, prioritize the consumption of calcium, potassium, and magnesium, and, most importantly, abstain from sodium.
At any given time, there are dozens of weight-loss hypes in the marketplace that claim to take off 10 pounds in 10 days, or whatever. Desperation can tempt us to try anything — from "clean eating" to cutting out food groups entirely. Keep in mind: Just because an avocado-kale-salad dripping in coconut oil is deemed "clean" by a so-called "expert" on your Instagram feed does not make it an unlimited food. Moral of the story? Avoid fads, eat real food, watch some Netflix, and unwind (perhaps with a glass of wine in hand). Now that's my kind of detox.

It’s important to do full-body strength training if you want to lose belly fat—especially if you’re trying to keep it off for the long haul. “Strength training should be a part of just about everybody’s exercise plan,” says Dr. Cheskin. That’s because strength training helps you build muscle, which will replace body fat. And because muscle is metabolically active, you'll continue to burn calories after working out, thereby, reducing overall body fat. Bonus: When your metabolic rate becomes faster due to muscle growth, you’ll have a little more wiggle room in your diet if that’s something you struggle with, says Dr. Cheskin.
And then there are WW’s “freebies.” The company recently incorporated the Zero-Point Foods concept to its dietary approach, a list of over 200 foods that do not have to be “tracked” or counted because they’re unlikely to be overeaten. (For example, one is more likely to binge on French fries than on chicken breasts). Examples of Zero-Point foods include skinless turkey breast, fish, shellfish, beans, tofu, lentils, corn, peas, fruits, vegetables, and non-fat unsweetened yogurt.

Even if you suffer from obesity, you don’t have to reach a “normal” BMI (more on this concept later) to reap the benefits that come with shedding some pounds. According to a Center for Disease Control and Prevention study, even a moderate weight loss ranging from 5 to 10 percent of the initial body weight can help you curb and prevent obesity-related illnesses. 
"These diets are so restrictive that of course you're going to lose weight fast because you're not eating enough calories to sustain basic activities of your body, let alone any exercise. That's nothing that any person can sustain for the long term," Hogan said. "The weight's going to come back if you do lose any weight, and then it's going to be harder to lose weight in the future."
“A lot of people think the foundation of a paleo diet is high-fat meat, but I suggest that it’s vegetables,” says Hultin. The concept is to eat only foods — including meat, fish, poultry, eggs, fruits, and vegetables — that would have been available to our Paleolithic ancestors. This means grains, dairy, legumes, added sugar, and salt are all no-no’s.
"How easy it is for someone to lose 10 pounds depends on a lot of things: age, gender, activity level, basal metabolic rate, and how much weight he or she has to lose" explains Kate Huether, MD, of The ReKovery MD, who also holds a master's degree in nutrition. "If someone is very overweight it is easier to lose excess weight as opposed to someone who is thinner," Dr. Huether adds.

"Whether it's an app or paper food logs, tracking what you eat will certainly be eye-opening. Almost everyone consumes more than they think. Write everything down as soon as you're done eating so you don't forget anything. The simple act of recording what you eat will make you eat less. When the calories are in your face, it makes you think twice!" — Martha McKittrick, RD, CDE

If you’ve been eating fast food for years, get real about your approach: You’re probably not going to stick to an organic, gluten-free, paleo overhaul for very long. "You want to change as little as possible to create calorie deficit," says Dr. Seltzer, who insists the best way to support sustainable weight loss is to incorporate small changes into existing habits. So instead of giving up your daily BLT bagels in favor of an egg-white wrap, try ordering your sandwich on a lighter English muffin. Or say you eat a snack bar every afternoon: Swap your 300-calorie bar for a 150-calorie alternative. "Your brain will feel the same way about it, so you won’t feel deprived," he says.
